the script editor edge is green but there's never any output other than "—-" (no acknowledgement that the function was created as it usually does), and the same thing happens for any subsequent inputs - no output.

Single line functions don't seem to trigger this behavior. Also it doesn't happen if I've just opened the Scala Tutorial story and cleared the editor.

Is there some way of entering this "full sala" mode without opening the Scala Tuturial?

The full scala mode is always on!

What you're seeing is the fact that - for single lines of code, Kojo works in verbose mode, whareas for multiple lines of code, Kojo works in non-verbose mode. In verbose mode, all output from the Scala interpreter is shown within the Output pane. In non-verbose mode, interpreter output is suppressed.

So, how is one supposed to work with this behavior (for multiple lines of code)? You have two options:
